Abstract
By the action of H2S on boron halides (other than fluoride) one obtains the new substitution products BX2SH, BX(SH)2, and B(SH)3 along with the corresponding hydrogen halide. These halogenosulfhydroboranes are unstable and cyclize to cyclic boron sulfides, either (BSSH)3 or (BSX)3.In the case of boron bromide it is possible, by controlling the ratio of the reactants and the temperature of the reaction, to promote the formation of one of the three possible substitution products. Then by encouraging cyclization one may obtain, rapidly and selectively, either (BSSH)3 or (BSBr)3.Synthesis of (BSCl)3 was accomplished by dissolution of (BSSH)3 in liquid BCl3 and that of (BSI)3 by the action of H2S on solid BI3.
